I wondered at that point if Arena is completely on autopilot. Code being like “just use the cards of Standard even if it’s not released yet in the UI but the cards exist internally”.
Though that’s probably wrong because they seem to have also done Arena changes with combined classes (“WarriorPriest” was hilariously good).
I think this is exactly how it works, because if you own a golden copy or two of some card you get in your arena run, it will be golden in your arena run as well
Wait. Could you always combine 2 classes in arena like this month? This is the first time I’m actually playing some Arena every day or two so I might had no idea about it.
